The cost of adaptability: resource availability constrains functional stability under pulsed disturbances
Global change exposes ecosystems to changes in the frequency, magnitude, and concomitancy of disturbances, which impact the composition and functioning of these systems. Here, we experimentally evaluate the effects of salinity disturbances and eutrophicati ...
Washington2024Towards a metabolic theory of catchments: scaling of water and carbon fluxes with size
Sara Bonetti, Francesca Bassani
Catchments are heterogeneous ecosystems involving several abiotic and biotic processes, where the mutual interactions among water, vegetation, and biogeochemical fluxes take place at different scales. Many biological processes in nature are characterized b ...
2023Explaining multiple patches of aquatic vegetation through linear stability analysis
Aquatic vegetation is ubiquitous in lowland rivers, and it is typically present in the shape of spatial self-organized patches of biomass. In this work, we mathematically define the threshold conditions for the incipient formation of self-organized vegetat ...
2022Towards simple tools to assess functional effects of contaminants on natural microbial and invertebrate sediment communities
Surface sediments can accumulate contaminants that affect microorganisms and invertebrates and disturb benthic ecological functions. However, effects of contaminants on ecological functions supported by sediment communities are understudied. Here, we teste ...
SPRINGER HEIDELBERG2020Invariant states in inclined layer convection. Part 1. Temporal transitions along dynamical connections between invariant states
Tobias Schneider, Florian Reetz
Thermal convection in an inclined layer between two parallel walls kept at different fixed temperatures is studied for fixed Prandtl number . Depending on the angle of inclination and the imposed temperature difference, the flow exhibits a large variety of ...
CAMBRIDGE UNIV PRESS2020Key rules of life and the fading cryosphere: impacts in alpine lakes and streams
Tom Ian Battin, Chenxi Wu, Jun Wen, Xiong Xiong
Alpine regions are changing rapidly due to loss of snow and ice in response to ongoing climate change. While studies have documented ecological responses in alpine lakes and streams to these changes, our ability to predict such outcomes is limited. We prop ...
2020Why choosing the right partner is important: stabilization of ternary Cs(y)GUA(x)FA((1-y-x))PbI(3)perovskites
Ursula Röthlisberger, Marko Mladenovic, Ariadni Boziki
Lead halide perovskites with mixtures of monovalent cations have attracted wide attention due to the possibility of preferentially stabilizing the perovskite phase with respect to photovoltaically less suitable competing phases. Here, we present a theoreti ...
ROYAL SOC CHEMISTRY2020Beyond the patch: on landscape-explicit metapopulation dynamics
Climate change threatens biodiversity and species distribution all over the world at unprecedented rates. Human induced changes to landscape structure and habitat are redefining the relation between species and their environment. Understanding, characteriz ...
EPFL2020Hydrological and Geomorphological Significance of Riparian Vegetation in Drylands
Drylands are regions encompassing hyperarid, arid, semiarid, or subhumid climatic conditions (see also Chap. 1). They include cold and warm subtropical deserts, savannas, and the Mediterranean environments. Our focus here is on warm drylands, which are gen ...
Springer Nature Switzerland2019A minimalist model of extinction and range dynamics of virtual mountain species driven by warming temperatures
Andrea Rinaldo, Enrico Bertuzzo, Damiano Pasetto, Jonathan Giezendanner
A longstanding question in ecology concerns the prediction of the fate of mountain species under climate change, where climatic and geomorphic factors but also endogenous species characteristics are jointly expected to control species distributions. A sign ...
